Pharmaceutical composition and functional health food for treating benign prostatic hyperplasia including laurus nobilis as active ingredient, and method of treating benign prostatic hyperplasia using the same

Abstract

The present disclosure relates to a pharmaceutical composition and a health composition including an effective amount of a bay leaf extract as an active ingredient for treatment and prevention of benign prostatic hyperplasia, and a method of treating benign prostatic hyperplasia using the same.

What is claimed is: 
     
         1 . A pharmaceutical composition comprising an effective amount of a bay leaf extract as an active ingredient for treatment and prevention of benign prostatic hyperplasia. 
     
     
         2 . A health functional food comprising an effective amount of a bay leaf extract as an active ingredient for treatment and prevention of benign prostatic hyperplasia. 
     
     
         3 . A method of treating benign prostatic hyperplasia comprising:
 preparing a pharmaceutical composition comprising an effective amount of a bay leaf extract an active ingredient; and   administering the pharmaceutical composition to a subject in need of treating the benign prostatic hyperplasia.   
     
     
         4 . The method of  claim 3 , wherein the preparing the pharmaceutical composition comprises extracting the bay leaf extract from a bay leaf using an extraction solvent. 
     
     
         5 . The method of  claim 4 , wherein the extraction solvent comprises an ethanol. 
     
     
         6 . The method of  claim 5 , wherein the ethanol is comprised in the extraction solvent in an amount of 30 vol % to 70 vol % based on a total weight of the extraction solvent. 
     
     
         7 . The method of  claim 3 , wherein the preparing the pharmaceutical composition further comprises:
 filtering the bay leaf extract extracted using the extraction solvent; and   lyophilizing and powdering the bay leaf extract into a powder.   
     
     
         8 . The method of  claim 7 , wherein the powder is dissolved in a solvent to prepare the pharmaceutical composition in a solution. 
     
     
         9 . The method of  claim 8 , wherein the solvent is dimethyl sulfoxide, distilled water, or a mixture thereof. 
     
     
         10 . The method of  claim 8 , wherein the solution is administered to the subject in an amount of 10 mg/kg to 50 mg/kg based on a body weight of the subject.
